How to grow Lemon Trees indoors: A step-by-step guide

Growing a lemon tree indoors in the UK is a rewarding way to bring a splash of sunshine to your home. Whether it’s the sweet scent of citrus blossoms or the thrill of picking your own fruit, lemon trees make excellent indoor companions – and thoughtful, lasting gifts. This step-by-step guide will help you grow a healthy lemon tree inside your home or greenhouse.

Our 5 step guide for growing a lemon tree indoors (in the UK)

Step 1: Choose the right variety of lemon tree

Some lemon tree varieties are better suited to indoor life than others. Look for compact, self-fertile trees that don’t need a partner for pollination. Great options include:

  • Meyer lemon
  • Lisbon lemon
  • Eureka lemon
  • Ponderosa lemon

All of these grow well in pots and will reward you with fruit and fragrance when cared for correctly.

Step 2: Provide the right growing conditions

Lemon trees thrive in warmth and light. Place your tree in the sunniest spot in your home – ideally a south-facing window. Use a high-quality potting mix blended with organic compost, and choose a container with good drainage. Adding 2 to 3 inches of mulch will help retain moisture and deter pests.

Step 3: Water and fertilise your lemon tree

Water your lemon tree only when the top inch of soil feels dry. Avoid waterlogging, and never let the pot sit in standing water. During the growing season (spring through late summer), feed your tree every two weeks with a citrus-specific or organic fertiliser.

Step 4: Prevent and treat pests and diseases

Keep an eye out for pests like scale insects or spider mites. These can cause leaf discolouration and drop. Wipe leaves gently with a damp cloth to remove pests early. If needed, treat with insecticidal soap. Prevent disease by avoiding overwatering and ensuring good airflow around the plant.

Step 5: Prune your lemon tree and harvest the fruit

Prune your tree each spring to maintain shape and encourage healthy growth. Remove any dead or crossing branches. Lemons are ready to pick when they turn fully yellow. Use sharp scissors to harvest – and enjoy your homegrown fruit fresh from the tree.

With patience and care, growing a lemon tree indoors is a deeply satisfying experience. Whether you’re nurturing one as a gift or for your own enjoyment, these sun-loving trees offer beauty, fragrance and flavour all in one compact package.
